A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

In this article, I will show you walkthrough example of download videos from Thinkific.

This Thinkific course uses Wistia to host all course videos. That means every Thinkific video ultimately loads as an HLS .m3u8 playlist, which you can download with yt-dlp.

PI is a TypeScript toolkit for building AI agents. It's a monorepo of packages that layer on top of each other: pi-ai handles LLM communication across providers, pi-agent-core adds the agent loop with tool calling, pi-coding-agent gives you a full coding agent with built-in tools, session persistence, and extensibility, and pi-tui provides a terminal UI for building CLI interfaces.

These are the same packages that power OpenClaw. This guide walks through each layer, progressively building up to a fully featured coding assistant with a terminal UI, session persistence, and custom tools.

By understanding how to compose these layers, you can build production-grade agentic software on your own terms, without being locked into a specific abstraction.

Pi was created by @badlogicgames. This is a great writeup from him that explains some of the design decisions made when creating it.

You've probably stumbled upon this researching how to remove the Xbox Game Bar. This gist includes a few different methods you can try. Please note that some of these first options are probably not be available unless you are running an older version of Windows 10.

EDIT: make sure to check out the comment below from @nmhung1985 which seems to be working for most folks.

(this is no longer an option on any recent Windows 10 build)

1. Press Windows Key or click on the Start menu.
2. Start typing Xbox or Game Bar, until you get the Xbox Game Bar app to appear in the results.

Write a handoff document summarising this session for future agents/sessions.

1. Determine today's date (use the currentDate context if available).

2. List the existing files under docs/agents/handoff/ to find the highest sequence number already used today, then increment by one. Format: NNN (zero-padded to 3 digits, starting at 001).

3. Use the current session name, otherwise derive a short kebab-case topic slug from the main subject of this session (e.g. eth-brownie-optimization, filter-sol-wsol-command).
